Want to grow ginger hydroponically? Here’s how

You have your hydroponic garden, and now you’re anxiously adding to it and need some hydroponic growing tips for an essential plant you plan to add to your cluster: ginger.

Ginger is an incredibly old plant that people have been growing for thousands of years. They use it for both medicinal and culinary uses, especially in Asian medicine and cuisine. Ginger usually grows in rich soils found in warm climates and it requires high humidity. However, if this doesn’t describe your area, there are ways you can mimic these conditions with a hydroponic system.

Ginger is called ginger root, but that’s not exactly correct. What’s really used to grow ginger is the rhizome of the plant, and from the rhizome, new leaves grow, and as the plant grows, so do new rhizomes. Most people assume you can grow ginger in water, and you can, but let’s break it down.


Is it safe to eat sprouted ginger?

Sprouting ginger doesn’t produce toxins the way sprouted potatoes do, but it also doesn’t offer the same nutritional value as fresh ginger. This is because bud growth causes the ginger to wilt and dry out. So although you can eat it, it’s not nutritionally beneficial to your diet. As it ages and shrivels, ginger also starts to have less flavor. For that reason, many people get rid of it or plant their ginger once it starts to sprout, instead of opting to cook with it or eat it.

Can I plant a sprouted ginger root?

Sprouted ginger is, in fact, one of the most ideal ways to plant ginger! When you plant ginger after it’s sprouted, it’s said to have a plentiful harvest. You’ll want to cut it into roughly 2-inch pieces before planting so that each piece has a couple of eyes it can grow from. The sprouted ginger will give you more ginger to plant and grow, thus resulting in more ginger to harvest.

The benefits of growing ginger hydroponically

There are numerous benefits to growing ginger in a hydroponic system. Here are just a few.

  • Hydroponic systems allow faster growth, as these provide constant and available nutrition. It helps plants grow up to 50% faster than if they were to grow in soil. Not only that, but hydroponic plants don’t have to worry about season changes, which means they can grow year-round.
  • Because hydroponic gardening removes the need for herbicides and pesticides used in soil gardening, it’s also better for the environment.
  • You can reuse the water in the hydroponic system, which reduces the need to use extra freshwater. Hydroponic systems can use less than 10% of the water compared to field-grown plants.
  • Gardening land around the world is in short supply. If you’re one of those people who doesn’t have the space for a big garden, hydroponics is the perfect solution because it lends itself well to indoor gardening for apartments, city living, or small houses.
  • Hydroponics allows for impressive space savings. Normally, a plant’s roots expand throughout the soil in search of food and oxygen. This doesn’t happen in a hydroponic system because the plant is directly in contact with an oxygenated nutrient solution and important minerals. What does that mean? It means you can grow plants much closer together and grow more of them.
  • Unlike leaving your plants outside in a garden, hydroponics allows for complete control of temperature, humidity, the intensity of the light, and even the composition of the air. This lets you grow any plant at all times of the year, regardless of the weather.

Are you convinced yet? If so, let’s jump right into how to grow hydroponic ginger. Don’t worry; we’ll give you a step-by-step rundown.

How to grow ginger hydroponically

Growing ginger hydroponically is not complicated. All it takes is patience, a few tools, and a lot of love.

To begin, you don’t need to root the ginger in water quite yet. Don’t worry, the ginger will grow hydroponically for most of its life, but it’s important to root the rhizome in compost first and then move it to a hydroponic system. First, cut the rhizome into several pieces with a bud on each. It’s a good idea to plant several to ensure germination. Fill a pot with compost, and then take your rhizomes and plant them roughly 1 inch into the soil. Water the plant on a regular basis. How do you know if your rhizomes have germinated? They will produce stems and some leaves.

  • While your rhizomes are germinating, you can prepare your hydroponic system to receive the ginger. Your container needs to be a decent size depending on how many plants you’re growing. Each plant requires 1 square foot of growing space, and the tray you use should be between 4 and 6 inches deep.
  • Once your rhizomes have germinated, remove the strongest ones from the soil and rinse off the roots. In your tray, put down 2 inches of soil, place your new ginger plants on top of the soil, and then spread out the roots (make sure to space each plant a foot apart). Pour more soil to cover the roots and hold the plants in place.
  • Hook up your system to water and feed your plants every 2 hours with a hydroponic nutrient solution, but you don’t need to be fancy, as any standard solution works. Regularly test the pH of the fluid to make sure it’s between 5.5 and 8.0. Put the plants in light for 16 to 18 hours a day and let them rest for 6 to 8 hours.
  • Within four months, the plants will produce more rhizomes and you can harvest them. Take the rhizomes, wash and dry them, and then store them in a cool, dry place.

There are incredible benefits to using a hydroponic system for ginger and any other plant. Anyone with patience and time can grow their own ginger without a big backyard or even a house. Hydroponic growing is the perfect solution for apartment dwellers with a green thumb, and by following these steps, you won’t ever have to buy ginger from the store again.

Tips and tricks for using water globes

Not being able to water your plants doesn’t have to mean instant death for them! Whether you’re going away for vacation or find yourself too busy to consistently water your plants, water globes for plants can be a reliable source of hydration for a few weeks. Plus, there are tons of colorful options, so no matter what your personal aesthetic is you're sure to find one that work for you. How useful are these gardening tools, and are they more effective than other watering methods? We'll answer all your questions and even recommend some of our favorite water globes!

What is a water globe?
The idea of a water globe is straightforward. Essentially, you have a sphere made from glass, plastic, clay, or metal with a long, thin neck. At the end of the neck, you'll find a small opening that slowly dispenses water after you fill up the globe and stick it into your soil. When your soil dries out, air gets into the globe, which pushes a small amount of water out of the stem.
Pros of water globes
Water globes are great if you’re going away for a while or find yourself without much time to tend to your plants. They can usually keep your soil moist for between seven to 14 days. If you’re out of town for a week or two or have a particularly thirsty plant, a water globe can be a quick and relatively affordable solution. It’s especially ideal for water-loving plants such as ferns and calatheas, which appreciate moist soil.
Cons of water globes
There are some matters to consider, of course. A globe can be fragile, especially if you get a glass one. Also, the amount of water dispensed can be variable, depending on how you stick the globe into the soil, the size of the sphere, and your home temperature conditions. While water globes dispense water slowly and don’t waterlog your soil, they aren't the best choice for plants that prefer to fully dry out between waterings, such as cacti and succulents.
